Abstract: 1,052,845. Brake master cylinders; dashpots. PATONS BRAKE REPLACEMENTS PROPRIETARY Ltd. Aug.14, 1963 [Aug.16, 1962], No.32201/63. Headings F2E, F2F and F2S. A master cylinder controlling the brakes of a trailer vehicle, in which the piston rod of the cylinder is combined with the coupling member for driving the trailer, has an electrically operated valve in the outlet passage from the cylinder to the trailer brake pipes, the valve being actuatable by the stop light circuit of the towing vehicle to permit the master cylinder to actuate the trailer brakes. Movement of the stopped piston and draw bar 13 to the left against the action of the spring 22 seats the tilted reservoir valve 28 and pressurizes the fluid in chamber 17 which passes through port 32, when the obstructing electromagnetic valve Fig. 2 (not shown), is opened by its energization from the stop light circuit, to actuate the brake lights. If the valve is not energized, for example when the stepped piston is moved to the left by the towing vehicle when reversing, the excess pressure is relieved by fluid returning to the reservoir 8 through valve 39. Subsequent movement of the piston to the right is damped by fluid which had entered chamber 41 through larger orifices in a ball valve 47 Fig. 3 (not shown), being forced to return to the reservoir through smaller orifices in the valve. A flange 18 on the piston abuts a resilient ring 21 on the cylinder body to transmit the towing force when the piston is fully returned to the right by the spring 22.

Abstract: 1,228,107. Automatic speed control. BELL & HOWELL CO. June 4, 1969 [June 5, 1968], No.28342/69. Heading G3R. The speeds of a tape recorder and a film projector are synchronized by means of an eddy current brake coupled to one of the motors. A sensor 11 reads pulses from an extra track on a tape record and delivers triggering pulses to one input R of a bi-stable circuit 15. A sensor 13 receives pulses from a reed switch 29 operated by the projector 19 and delivers triggering pulses to the other input S of the bi-stable 15. The output of the bi-stable is amplified and feeds the coil of an eddy current brake 23. When tape and film are synchronized the bi-stable delivers a symmetrical squarewave; if synchronism is lost the mark/space ratio of the squarewave alters to increase or decrease the energization of the brake. Where the projector is driven by a shaded pole induction motor the brake may be a similar motor whose armature is fed with the D.C. output of the amplifier; the rotors of the two motors may share a common shaft, Fig.4, (not shown) or be coupled by a belt, Fig.5, (not shown). It is pointed out that the frequency of pulses recorded on the tape may be varied so that the projector follows a predetermined programme.
